ADDING-MACHENE.

SFECJTFICATItdN forming part of Letters Patent No. 322,190, dated July14, 1885.

Application filed September 6, 1884.

To aZZ whom it may concern:

Be it known that I, XVILLIAM JOHN Mne- NTDER, of Greensborough, in thecounty of Green and State of Georgia, have invented a 5 new and ImprovedAdding-Machine, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a new andimproved machine bymeans of which 1 columns of figures can be added very rapidly andaccurately.

The invention consists in the combination, with a series ofcounting-wheels, of a toothed wheel adapted to engage with thecountingwheels, and mounted on a shaft having one end journaled in aswinging standard, which swinging standard is connected by a suitablelever with a push-pin, by means of which the toothed wheel can be swungtoward and from the counting-wheels. The shaft on which thecounting-wheels are mounted is journaled in a carriage adapted to slidetransversely, and is provided with a handle-piece projecting through atransverse slotin the top of the box,

atoothed wheel operated from aseries of pushpins by ratchet-wheels,pawls, and levers being adapted to engage with the severalcounting-wheels and revolve them. The wheels are brought back to theirnormal position by means of a series of cog-wheels mounted on a swingingshaft, and adapted to engage with pins on the counting wheels, theswinging shaft being swung by suitable devices toward the shaft carryingthe countingwheels at the 5 same time that it is revolved.

The invention also consists in various parts and details andcombinations of the same, as will be fully set forth and claimedhereinafter.

Reference is to be had to the accompanying o drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional plan view of my improved adding-machine. Figs. 2and 8 are longitudinal sectional elevations of the same on the lines 00x and yyof Fig. 1, respectively. Fig. 4 is a plan view on a smallerscale. Fig. 5 is a side view of one of the hubs. Fig. 6 is a side viewof one of the counting-wheels. Fig. 7 is a plan view of thetransverselysliding carriage, the standards with the shaft and (Model)counting-wheels being broken away to show the rack.

The entire mechanism is contained in a box', A, and on the upper surfaceof the bottom of the box a standard, B, is pivoted, near one side of thebox, and at the other side a stand,- ard, D, is secured, in whichstandards a shaft, 0, is mounted to turn, the opening in the standard B,being such as to permit the shaft O to swing slightly in the horizontalplane. On the shaft 0 are rigidly mounted nine ratchet-wheels, D, andadjoining each ratchet-wheel a lever, D, is mounted to rock on the shaft0, in each of which levers D a pawl, D, is pivoted, which is pressed bya suitable spring, d, against the teeth of its wheel D. Each rocking orswinging arm or lever D is connected by a wire, E, with an arm or lever,E, pi'voted on a suitable standard, E", and pressed upward by a spring,E. The wires E and the levers E are of different lengths, so that fromthe same vertical throw of the different levers E the ratchct-wheels Dconnected therewith will be turned different distances, 7 theratchet-wheel D of the first lever being thrown only one-ninth of thedistance that the ratchet-wheel of the ninth lever is thrown. From theseveral levers E rods or push-pins F project upward through the top ofthe box A, and are provided at their upper ends with suitable heads, F,the rods F being provided below the top of the boxwith crosspieces a,forming checks to prevent the rods or pushpins F from being thrownupward too far. The push-pins F and their heads F are arranged in tworows, the even numbers being in one row and the odd numbers in the otherrow. The numbers corresponding to the several levers are produced on theheads F, as shown in Fig. 4-. The rocking or pivoted standard 13 isconnected by a lever, b, with one end of an elbow-lever, b, pivoted atits elbow on a block, b", on the bottom of the box,

in the other end of which elbow-lever a rod 5 or push-pin, G, ispivoted, which projects up through the top of the box, and is providedon its upper end wit-h a head, G. A spiral spring, G", surrounds the rodor push-pin G above the top of the box, and presses the same we upward.On the shaft 0 awhcel, H, is rigidly mounted, which is provided on itsrim with triangular or other teeth H. Two standards, I, united by asuitable bottom-plate, are held to slide transversely on a support, I,in the bottom of the box, and in the said standards a shaft, J isjournalcd, on which a series of hubs, K, are rigidly mounted, each hubbeing provided with a recess, K, in one side and at the rim, therecesses being shown in side view in Fig. 5 and in top view in Fig. 1.Adjoining each hub a wheel, L, is loosely mounted on the shaft J, eachwheel L being provided with a circular row of ten pins, Z, projectingover the hub K corresponding to the wheel, and between the ten pins Znine shorter pins, m, are arranged so that an open or blank space, Z,will be left between two of the longer pins. On that surface of eachwheel L opposite the one from which the pins project a pawl, plate, ordog, M, is pivoted, the free end of which is connected with a spring, M,secured on the side of the wheel, and throwing the outer end of-the saidpawl, plate, or dog M outward, so that when it comes opposite to therecess K in the hub the said pawl or dog can enter the recess and engagewith the long pins Z of the adjoining wheel L. The spring M is apressure-spring, which is secured to the wheel at two points, and hasone end bent rectangir larly, the bent end resting against the pawl andbeing adapted to throw the same outward from the side of the wheel. Fromone of the standards I an a rm,J, projects upward through a transverseslot, N, in the top of the box,and is provided at its upper end with ahandle, J. The slot N is so arranged that it is directly over the shaftJ. On the rim of each wheel L the numbers from 1 to O, inclusive, areprod need. A rack, O, is formed on the front edge of the board or plateuniting the standards I, and against the said rack a pawl, O, is pressedby a spring, 0*, the said pawl being pivoted on a suitable standard, O",projecting upward from the bottom of the box A. A wire, 0", connects thepawl O with the swinging standard B. A spring, P, connected with one ofthe standards I, pulls the frame formed by the standards and theirbottom connectin plate toward the right. the box two standards, Q, arepivoted on the bottom of the box to swing in a vertical plane, and areunited by a cross-piece, Q, and by a shaft, Q jourualed in the top ofthe standards Q. On the shalt Q are mounted as many cogwheels, It, asthere are wheels L on the shaft J, the said wheels B being adapted topass in between the wheels L and engage with the long and the short pinsZm on the said wheels L. On one end of the shaft Q is mounted a pinion,R', adapted to engage with an internal gear-wheel, R pivoted upon one ofthe stand ards Q and an arm, Q, of the same, the said internalgear-wheel, It, being connected by a fixed sleeve or cam or otherwisewith a pinion, S. In an uprigh t guide or standard, T, a bar, T, is heldto slide vertically, the said bar projecting through the top of the boxand being provided at its upper end with a head, T.

In the rear part of On the bar T a rack, 91, is formed, and from thelower end of the said bar a pin, 0, projects. A lever, U, pivoted on thebottom of the box has one end connected by a wire, 0', with a lever, U,pivoted 011 and projecting from the standard T. The other end of thelever U is connected with a lever, \V, whose opposite end is connectedwith the middle of a toggledever, XV, having one of its ends connectedwith the bottom of the box or a frame on the same, and the other endwith the cross-piece Q uniting the rocking standards Q.

The operation is as follows: The rods or push-pins F are all depressedthe same distance and throw the corresponding levers, ll, through thesame are; but'as the lengths of the several levers E vary,the rockingarms or levers D connected therewith by the several wires E will bethrown differeet distances. For instance, if the push-pin marked 2, Fig.l, is depressed, the wheel 11 will be revolved the distance of twoteeth, and if the puslrpin marked 8 is depressed, the wheel H will berevolved the distance of eight teeth, and so on. For instance, if thenumbers 2, l, 5, and 8 are to be added, the pins marked 2, 1, 5, and 3are depressed successively, whereby the wheel H is moved the distance ofeleven teeth, and as its teeth engage with the long pinsZ of the firstwheel L the said wheel will be revolved the distance of eleven teethorpins. hen the first wheel L has been revolved the distance of ten teeth,its pawl, plate, or dog M, coming in line with the recess in the hub, isswung outward by the spring M and passes into the notch Kof theadjoining hub K, and thus engages with a pin, Z, of the adjoining orsecond wheel L, thereby turning the second wheel the distance ofonespace, so thatthe number 1 will show on the second wheel and 1 will showon the first wheel through the slot N. As the first column amounted toeleven, the first wheel L is no longer required, and must be shifted outof use. To accomplish this, the puslrpin or rod G is pressed downward,whereby the standard B is swungfrom theshaft J, and the wheel H isdisengaged from the first wheel L, and at the same time the pawl O isdis engaged from the rack O for ashortti me, thus permitting the spring1 to pull the carriage in which the shaft J is journaled to the right,the handle J being used to hold the carriage at the distance of onetooth, whereby the wheel H will be engaged with the second wheel L. Assoon as the carriage has been shifted the standard Bis swung to thefront again. As the second wheel has been moved the distance of onetooth or pin Z, or one numher on the periphery of the wheel, and thenumeral 1 of the second wheel shows through the slot N, the one which isusually carried from the eleven need not be carried, as this was doneautomatically. The second column is added in a like manner, and whencompleted the adding-wheels are again shifted, and so on.

I have shown only four adding-wheels, but

as many as may be desired may be provided. The result will at all timesshow through the slot N in the top of the box. After the sums have beenadded,and the parts of the addingmachine are to be brought back intotheir original normal positions, the carriage carrying the shaft J ispushed to the left by means of the handle J until the wheel H can againengage with the first wheel L. The addingwheels L are always to be soadjusted that the zeros may show through the slot N. To accomplishthis,the rod T is pulled upward and the pin 0 strikes the arm U, therebypulling upward the front end of the arm U and downward the rear end,whereby the end of the lever WV connected with the arm U will be forceddownward, and the end connected with the toggle-lever WV is movedupward, whereby the standards Q and the parts on them will be swungtoward the shaft J and the wheels R on the shaft Q will be engaged withthe pins land m. By pressing the rod T downward the rack 12, which isnow engaged withthe pinion S, by swinging the standards Q toward theshaft J revolves the said pinion, and by means of the intermediategearing revolves the shaft Q and the cog-wheels R thereon. The saidcog-wheels revolve the wheels L, and as each wheel L is provided with ablank space between two long pins Z the eog-wheelsR can only revolve thewheels L until the cogs of the wheels B have come opposite to the blankspaces. The blank spaces are all so arranged that when the cogs of thewheels R arrive at the same all the wheels L show zero through the slotN. As the rod T is pushed downward its pin 0 strikes the front end ofthe lever U and presses the same downward, thereby pressing the rear endupward and pressing the middle of the toggle lever downward, whereby thestandards Q are swung from the shaft J and the wheels R thus disengagedfrom the pins on the wheels L. The machine is now ready for operation.

I have shown the toothed wheel H on one end of the shaft 0 and the pushpin or rod G in a corresponding position; but, if desired, the wheel Hcan be arranged on the middle of the shaft 0 and the heads F of theseveral push pins or rods F arranged at both sides of the rod G.
